I have a pair of Bristletail Filefish that I bought from Divers Den for $60. They are known to eat aiptasia but have not eaten a single one in my tank. One of them nips at my palys. Asking $40 for the pair

I also have a 2 inch ocellaris clownfish for $10. I will also consider a trade for zoas that I don't have.
